Unity Wroe rounds up the best on stage in Sussex over the next seven days.

The Mikado, Theatre Royal, Brighton, until July 6.

Gilbert and Sullivan's operetta is the longest-running musical ever written in Britain.

Written in 1885, with a host of colourful characters and memorable songs, The Mikado was an instant hit with theatre-goers. With an extravagant set and wardrobe, this version, performed by the acclaimed Carl Rosa Opera Company, is set to follow suit.

Tickets cost £13.50 to £22.50. Call 01273 328488.

Taking Steps, Devonshire Park Theatre, Eastbourne, until July 27.

Set in a rotting old house, this early Ayckbourn comedy follows six misfits over the course of a night and the following day as they entangle themselves in a melee of suicide notes, mistaken identities and punch-ups.

At the forefront of the confusion are rich cad Roland (Tony Adams) and his much younger wife Elizabeth (Amanda Humphrey).

Tickets cost £ £10 to £15. Call 01323 412000.

Spot's Birthday Party, Dome Concert Hall, Brighton, July 11-13.

The lovable pup and his pals are brought to life in this production aimed at children aged two to five.

In this show, Spot, Steve the monkey, Helen the hippo and Tom the crocodile manage to create mountains of birthday mischief.

Based on the books by Eric Hill, the audience will be treated to songs, music and magic.

Tickets cost £7 (£5 children), some group concessions also available. Call 01273 709709.

Rockin' on Heaven's Door, Theatre Royal, Brighton, July 7 This three-hour rock fest brings together Elvis, Buddy Holly, Roy Orbison and Eddie Cochran.

Well, not the real ones, obviously, but sound-and-look-a-likes who can pull together a fine rendition of their idols at any rate. The show takes the audience back to the sounds of the Seventies, promising to culminate in one heck of a finale.

Tickets cost £10, £12 and £14. Call 01273 328488.
